The Power Report (Part 4): Humans Beat Computers in First “Igo Electrical King Tournament”; Kataoka

by John Power, EJ Japan Correspondent
Humans Beat Computers in First “Igo Electrical King Tournament”: To test how close computers have come to human level at go, the first Igo Electrical King Tournament was staged in the top playing room, Yugen, at the Nihon Ki-in on February 11. Please take our word that “electrical king” (dennou) sounds better in the original.  The program Zen played best-of-three 9x9 matches with Cho Riyu 8P and Hirata Tomoya 3P, but lost both without picking up a game. However, Zen lost by only half a point in its first game with Cho, and human commentators pointed out a winning sequence that it missed in the endgame. One of Zen’s programmers commented that it would still take ten years to catch up with pros in 9x9 go.
 Zen vs. Hirata Tomoya 3P: Game 1. Hirata (W) by resig.; Game 2. Hirata (B) by resig. Zen vs. Cho Riyu 8P: Game 1. Cho (B) by half a point; Game 2. Cho (W) by resig. 
More games in this tournament were played three days later on 13x13 and 19x19 boards. On the 13x13, Emura Koki (W), a former WAGC representative for Japan, twice beat Zen by resignation. On the 19x19, Zen beat Ozawa Ichiro, a prominent politician. He is dan level, but we don’t know his exact rank. 
Kataoka Scores 1,000 Wins: A win on February 27 gave Kataoka Satoshi 9P (right) his 1,000th win as a pro, making him the 15th Nihon Ki-in player to reach this mark. It took him 42 years and his record was 1,000 wins, 530 losses, 4 jigo. 
Retirements: Two more veteran players have retired as of March 31. They are Ishida Akira 9P and Fukui Susumu 9P. Ishida was born in Tokyo on May 23, 1949 and became a disciple of Fukuda Masayoshi 8P. He became 1-dan in 1966 and 9-dan in 1982. He won the top section of the rating tournament (Oteai) in 1972 and the 3rd and 4th King of the New Stars titles ((1978 and 1979). He played in six Meijin leagues and one Honinbo league. At his peak, when he played in the Meijin league for six years in a row, Ishida impressed as one of the top players on the go scene, but he never put it together to win a big title. Fukui was born in Tokyo on May 21, 1947 and became a disciple of Iwamoto Kaoru. He became 1-dan in 1965 and 9-dan in 1994. His older brother, Masaaki, is still active.
